Overview of the Cold Spell in Thailand
Thailand is bracing for a prolonged cold spell that is anticipated to last until mid-February 2025. This weather phenomenon is primarily attributed to the La Niña effect, which has brought about significant changes in temperature and precipitation patterns across the country.
Causes of the Cold Weather
La Niña Phenomenon Impact
According to environmental experts, Thailand entered the La Niña phase last month. This climatic condition has resulted in southern and southeastern winds covering the nation, leading to increased humidity and a higher likelihood of thunderstorms from February through May.
Polar Vortex Influence
Additionally, a polar vortex originating from China has caused temperatures in some provinces to drop into single digits. This phenomenon involves a large area of cold air circulating around the polar regions, which can influence weather patterns far from its origin.
Forecast for Upcoming Months
Temperature Expectations
Experts predict that the highest temperatures during March and April will be lower than usual due to the combination of high humidity and increased rainfall. This year’s summer is expected to be milder compared to previous years.
Rainfall Projections
The Thai Meteorological Department forecasts that rainfall in April and May will exceed levels seen in prior years, with some rain also expected in June. The presence of a strong high-pressure system from China will further contribute to these conditions, bringing cooler temperatures and strong winds across various regions.
Regional Weather Conditions
Northern and Central Regions
Cool mornings are anticipated in northern, northeastern, and central Thailand, including Bangkok. Morning fog may affect visibility during this period.
Southern Provinces
In southern Thailand, the Northeast monsoon is likely to produce isolated heavy rains and waves reaching two meters high. Residents are advised to stay alert for potential thunderstorms as conditions evolve.
